A '''Bangalore torpedo''' is an [[explosive]] charge placed within one or several connected tubes. It is used by [[combat engineer]]s to clear obstacles that would otherwise require them to approach directly, possibly under fire. It is sometimes colloquially referred to as a "Bangalore mine", "banger" or simply "Bangalore" as well as a '''pole charge'''.

Per [[United States Army Field Manual]] 5-250 section 1-14, page 1-12 "b. Use. The primary use of the torpedo is clearing paths through wire obstacles and heavy undergrowth. It will clear a 3- to 4-metre wide path through wire obstacles."

The Bangalore torpedo was later adopted by the [[United States Army|U.S. Army]] during [[World War II]], as the "M1A1 Bangalore torpedo". Bangalore torpedoes were packed in wooden crates that contained 10 torpedo sections, 10 connecting sleeves, and 1 nose sleeve; the total weight of a crate was 176 pounds (80 kg). Each torpedo section was 5 feet (1.5 m) long, 2.125 inches (54 mm) in diameter, and weighed 13 pounds (5.9 kg). Each end of the torpedo was filled with 4 inches (102 mm) of TNT booster, while the middle section contained an 80-20 [[amatol]] mixture; the explosive charge weighed about 9 pounds (4.1 kg). Each end of the torpedo had a recess to accommodate a standard [[United States Army Corps of Engineers|Corps of Engineers]] blasting cap. Torpedo sections could be attached together via spring clip-equipped connecting sleeves, and a blunt nose sleeve was provided so that the assembled torpedoes could be pushed through obstacles or across terrain without getting stuck.

It was widely used by the U.S. Army, notably during the [[Normandy landings|D-Day landings]]. The Bangalore torpedo was obsolete in British use at the time of [[Normandy landings|D-Day]], having been replaced by rocket-launched [[Mine-clearing line charge|Congers]] and [[Armoured Vehicle Royal Engineers]] (AVRE) vehicles equipped with a {{convert|40|lb|kg|adj=on}} explosive charge for bunker clearing.{{citation needed|date=November 2012}}

Newer Bangalore variants include the Alford Technologies Bangalore Blade and the Chemring Advanced Performance Bangalore Torpedo (APBT), with both of these having been developed in the United Kingdom. The Bangalore Blade is made from lightweight aluminium and is configured as a linear explosively formed projectile (EFP) array capable of cutting wire obstacles which earlier Bangalore variants were incapable of breaching effectively; the improvements introduced with the Bangalore Blade give the charge a cutting action as well as a blasting effect. In a test detonation conducted on the [[television]] show ''[[Future Weapons]]'', the Bangalore Blade blasted a gap roughly five meters wide in [[concertina wire]], and created a trench deep enough to detonate most nearby anti-personnel mines. Alford Technologies' web page for the Bangalore Blade cites additional trial detonations involving two identical triple-razor wire entanglements erected between steel pickets; a Bangalore torpedo conforming to the original design cleared a three metre path, while the Bangalore Blade cleared a ten metre path.<ref>{{cite web |author = Alford Technologies |title = Bangalore Blade |url= https://explosives.net/product/bangalore-blade/ |access-date= 20 January 2020 }}</ref> The Advanced Performance Bangalore Torpedo also uses an aluminium body and is filled with two kilograms of DPX1 high density pressed explosive; a unique and patented design feature is incorporated which, in combination with the DPX1 explosive, provides enhanced blast and fragmentation effects which in turn provide an enhanced cutting capability against both simple and complex wire entanglements. The APBT is capable of cutting through up to six millimetres of steel plating. Up to eight APBTs can be combined with one another, with the resulting assembly capable of defeating obstacles that are up to eight metres in length; the quick-turn thread used for this purpose has been designed for ease of assembly when contaminated with sand, soil, or mud whilst being strong enough to ensure reliable deployment of connected charges without inadvertent decoupling.<ref>{{cite web |author = Chemring Energetics UK |title = AP Bangalore Torpedo |year= 2016 |url= https://www.chemring.co.uk/~/media/Files/C/Chemring-V3/documents/energetics/bangalore-torpedo-apbt-.pdf |access-date= 20 January 2020|author-link = Chemring Group }}</ref> The APBT also has an improved [[Insensitive munition|Insensitive Munition]] signature compared to preceding in-service designs.<ref>{{cite web |author = Chemring Energetics UK |title = Bangalore Torpedo Replacement |year= 2010 |url= https://imemg.org/wp-content/uploads/IMEMTS%202010/presentations/im_systems_4_Young.pdf |access-date= 1 July 2020|author-link = Chemring Group }}</ref>
